Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of health care apparatuses, and in particular, to a connecting device and a massage device. BACKGROUND

[0002] As health care apparatuses for relieving or eliminating body fatigue, massage devices are increasingly favored by people due to their flexible and convenient use. In order to obtain better massage effect, targeted massage devices are usually designed according to the structural characteristics of each part of the human body, such as neck massage devices, waist massage devices, shoulder and neck massage devices, etc. As people spend more and more time sitting at work and in life, people are prone to muscle discomfort at the same time, so the market demand for massage devices that can massage muscles is increasing.

[0003] In related technologies, some massage devices drive massage heads to move through eccentric wheels and other transmission assemblies. However, when the massage heads are arranged above the transmission assembly to move, in order to avoid interference, enough avoiding space needs to be reserved near the transmission assembly, which leads to a relatively bulky overall massage device, which is not conducive to the miniaturization of the massage device. UTILITARIAN CONTENT

[0004] The present disclosure provides a connecting device and a massage device. The connecting device can effectively reduce the movement interference near the transmission assembly, has a compact structure, and is conducive to the miniaturization of the massage device.

[0005] The technical scheme is as follows: According to a first aspect of an embodiment of the present disclosure, a connecting device is provided, which includes a bearing assembly, a transmission assembly, and a rotating member. The bearing assembly is provided with a first mounting portion. The transmission assembly includes an eccentric wheel in rotational connection with the bearing assembly and a transmission member movably arranged on the bearing assembly. The transmission member is provided with a transmission body and a transmission ring sleeved on the outer side of the eccentric wheel. One end of the transmission body is fixedly connected with the transmission ring, and the other end is provided with a transmission portion spaced apart from the first mounting portion, and the transmission portion is provided with a transmission hole. The rotating member is hingedly connected with the first mounting portion. One end of the rotating member is provided with a rotating portion, and the other end of the rotating member is provided with a connecting portion for connecting with a first massage head. The rotating portion is at least partially spherical and is rotatably arranged in the transmission hole. The rotating portion can slide along the depth direction of the transmission hole, and part of the rotating member passes through the first mounting portion, so that the connecting portion is arranged outside the bearing assembly. When the eccentric wheel rotates, the eccentric wheel rotates eccentrically with the transmission ring to drive the rotating member to rotate through the transmission portion, and the rotating portion can reciprocally slide along the depth direction of the transmission hole.

[0006] The technical scheme of the present disclosure will be further described below: In one of the embodiments, the first mounting portion comprises a mounting cavity, a first avoiding opening communicated with the mounting cavity, and a second avoiding opening communicated with the mounting cavity. The first avoiding opening and the second avoiding opening are arranged on the side wall of the mounting cavity and spaced apart in the first direction. The rotating member is pivotally connected with the mounting cavity, and a part of the rotating member passes through the first avoiding opening so that the rotating portion is arranged below the first avoiding opening. A part of the rotating member passes through the second avoiding opening so that the connecting portion is arranged above the second avoiding opening.

[0007] In one of the embodiments, the rotating member comprises a shaft body, and the side wall of the mounting cavity is provided with a hinge hole pivotally connected with the shaft body.

[0008] In one of the embodiments, the bearing assembly comprises a first bearing member provided with a first avoiding recess and a first recess, and a second bearing member provided with a second avoiding recess and a second recess. The first bearing member and the second bearing member are fixedly connected so that the first avoiding recess and the second avoiding recess cooperatively form the mounting cavity, and the first recess and the second recess cooperatively form the hinge hole. The first avoiding opening is arranged on the first bearing member, and the second avoiding opening is arranged on the second bearing member.

[0009] In one of the embodiments, the first bearing member comprises a first bearing body provided with the first avoiding recess and the first recess, and a second bearing body fixedly connected with the first bearing body. The eccentric wheel is rotatably arranged on the second bearing body so that the transmission portion and the mounting cavity are spaced apart in the first direction.

[0010] In one of the embodiments, the bearing assembly further comprises a bearing shell. The bearing shell is fixedly connected with the first bearing member to form a protective cavity for the transmission assembly and the rotating member. The mounting cavity is communicated with the protective cavity through the first avoiding opening.

[0011] In one of the embodiments, at least one of the bearing shell and the second bearing body is provided with a second mounting portion spaced apart from the first mounting portion in a second direction. The second direction intersects with the first direction, and the second mounting portion is rotatably connected with the eccentric wheel.

[0012] In one of the embodiments, the rotating portion is capable of swinging in the direction close to or away from the rotation axis of the eccentric wheel, and the transmission hole is a cylindrical hole. A first conical recess for avoiding the rotating member is arranged in the cylindrical hole, and the first conical recess is arranged close to the first conical recess of the eccentric wheel. And / or, a second conical recess for avoiding the rotating member is arranged in the cylindrical hole, and the second conical recess is arranged away from the first conical recess of the eccentric wheel.

[0013] In one of the embodiments, the rotating member comprises a hinge portion pivotally connected with the first mounting portion, and a first rod body fixedly connected with the hinge portion. The rotating portion is arranged on the free end of the first rod body. The first conical recess and the second conical recess are used for avoiding the first rod body.

[0014] According to a second aspect of the present disclosure, a massage device is also provided, including a housing assembly, a first massage head, a power mechanism, and a connecting device as described in any of the above embodiments. A supporting assembly is fixed to the housing assembly. The first massage head is connected to a connecting portion. The power mechanism is disposed on the housing assembly and drives a rotating component to move via a transmission assembly.

[0015] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: When a massage is needed, the power mechanism generates power, which drives the eccentric wheel to rotate via the transmission assembly. The eccentric wheel engages with the transmission ring to rotate the rotating component via the transmission part, allowing the rotating component to slide back and forth along the depth direction of the transmission hole. This, in turn, drives the first massage head to oscillate back and forth, achieving at least a reciprocating pushing massage effect. Because the rotating component is directly hinged to the housing assembly shaft and directly slides through the transmission hole via the transmission part, it can utilize eccentric driving force to drive the oscillation of the rotating component while reducing motion interference and simplifying the transmission components between the rotating component and the transmission part. Thus, this connecting device has a compact structure, which is beneficial for miniaturizing the massage device.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0031] To better understand the connection device of this disclosure, it will be described using a massage device in which the connection device is applied.

[0032] like Figures 1 to 4 As shown in the embodiments of this disclosure, a massage device 1 is provided, including a housing assembly 10, a first massage head 20, a power mechanism 30, and a connecting device 40. The connecting device 40 includes a support assembly 100, a transmission assembly 200, and a rotating member 300. The support assembly 100 is provided with a first mounting portion 110. The transmission assembly 200 includes an eccentric wheel 220 rotatably connected to the support assembly 100 and a transmission member 210 movably disposed on the support assembly 100. The transmission member 210 is provided with a transmission body 211 and a transmission ring 212 sleeved on the outside of the eccentric wheel 220. One end of the transmission body 211 is fixedly connected to the transmission ring 212, and the other end is provided with a transmission portion 213 spaced apart from the first mounting portion 110, and the transmission portion 213 is provided with a transmission hole 201. The rotating member 300 is hinged to the first mounting portion 110. One end of the rotating member 300 is provided with a rotating portion 310, and the other end of the rotating member 300 is provided with a connecting portion 320 connected to the first massage head 20. The rotating part 310 is at least partially spherical and rotatably disposed within the transmission hole 201. The rotating part 310 is also capable of sliding along the depth direction of the transmission hole 201. A portion of the rotating member 300 passes through the first mounting part 110, allowing the connecting part 320 to be disposed outside the support assembly 100. When the eccentric wheel 220 rotates, the eccentric wheel 220 engages eccentrically with the transmission ring 212, thereby driving the rotating member 300 to rotate via the transmission part 213, and enabling the rotating part 310 to reciprocate along the depth direction of the transmission hole 201. The power mechanism 30 is disposed on the housing assembly 10 and drives the rotating member 300 to move via the transmission assembly 200.

[0033] When massage is needed using the massage device 1, the power mechanism 30 generates power, which drives the eccentric wheel 220 to rotate via the transmission assembly 200. The eccentric wheel 220 engages with the transmission ring 212 to rotate the rotating component 300 via the transmission part 213, allowing the rotating component 310 to slide back and forth along the depth direction of the transmission hole 201, thereby driving the first massage head 20 to oscillate back and forth, achieving at least a reciprocating pushing massage effect. Since the rotating component 300 is directly hinged to the housing assembly 10 shaft and directly slides with the rotating component 300 through the transmission hole 201 via the transmission part 210, it can both drive the rotating component 300 to oscillate using eccentric driving force and reduce motion interference, simplifying the transmission components between the rotating component 300 and the transmission part 210. Thus, the connecting device 40 has a compact structure, which is beneficial for miniaturizing the massage device 1.

[0034] Understandably, the cooperation between the transmission ring 212 and the transmission body 211 makes the transmission part 213 and the eccentric wheel 220 spaced apart, which not only prevents the movement of the rotating part 300 from interfering with the movement of the eccentric wheel 220, but also makes the structure of the transmission assembly 200 compact and occupies little space.

[0035] Furthermore, the first massage head 20 is independently assembled on the connecting device 40 via the connecting part 320, and will not interfere with the moving components such as the power mechanism 30 and the transmission component 200 on the housing assembly 10. This also makes it possible for the massage device 1 to not require a large amount of clearance space, resulting in a compact structure and facilitating further miniaturization of the massage device 1.

[0036] It should be noted that "shaft hinge" should be interpreted broadly, including the use of structures such as rotating shafts and shaft bodies 331 to enable two rotating parts 300 to rotate around an axis.

[0037] It should be noted that the "connecting part 320" can be implemented in various ways, including but not limited to snap-fit ​​parts, plug-in parts, fixed shafts, welding rods, etc., and can be flexibly rotated according to the installation requirements of the first massage head 20.

[0038] like Figure 4 as well as Figure 6As shown, in some embodiments, the first mounting portion 110 includes a mounting cavity 111, a first clearance opening 112 communicating with the mounting cavity 111, and a second clearance opening 113 communicating with the mounting cavity 111. The first clearance opening 112 and the second clearance opening 113 are spaced apart along a first direction on the side wall of the mounting cavity 111. The rotating member 300 is hinged to the mounting cavity 111, and a portion of the rotating member 300 passes through the first clearance opening 112, so that the rotating portion 310 is disposed below the first clearance opening 112. A portion of the rotating member 300 passes through the second clearance opening 113, so that the connecting portion 320 is disposed above the second clearance opening 113. In this way, the rotating member 300 is confined within the mounting cavity 111, and the internal space of the supporting assembly 100 can be fully utilized to accommodate the rotating member 300, so that the two fit tightly. Meanwhile, by providing the first clearance opening 112 and the second clearance opening 113, the rotating member 300 can be installed through the first clearance opening 112 and the second clearance opening 113, so that the rotating part 310 and the connecting part 320 can also be spaced apart along the first direction, and thus the first massage head 20 connected to the connecting part 320 will not interfere with the movement of the transmission member 210 connected to the rotating part 310.

[0039] Optionally, such as Figures 4 to 6 As shown, in some embodiments, the rotating member 300 includes a shaft 331, and the side wall of the mounting cavity 111 is provided with a hinge hole that is hinged to the shaft 331. Thus, through the engagement of the shaft 331 and the hinge hole, the rotating member 300 can easily rotate around the axis of the shaft 331, facilitating the reciprocating oscillation of the first massage head 20 along a predetermined arc trajectory via the oscillation of the rotating part 310. For example, when the first massage head 20 is used to massage a user's neck, arms, or thighs, it can squeeze the neck muscles, arm muscles, or thigh muscles to achieve a muscle-relaxing effect.

[0040] Furthermore, such as Figures 4 to 6As shown, in some embodiments, the support assembly 100 includes a first support member 120 having a first clearance concave surface 1211 and a first groove 1212, and a second support member 130 having a second clearance concave surface 131 and a second groove 132. The first support member 120 and the second support member 130 are fixedly connected such that the first clearance concave surface 1211 and the second clearance concave surface 131 cooperate to form a mounting cavity 111, and the first groove 1212 and the second groove 132 cooperate to form a hinge hole. A first clearance opening 112 is provided in the first support member 120, and a second clearance opening 113 is provided in the second support member 130. Thus, when assembling the rotating component 300 with the supporting assembly 100, the rotating component 300 is placed on the first clearance concave surface 1211, and the shaft 331 is placed in the first groove 1212. Then, the second supporting component 130 is fixedly connected to the first supporting component 120, so that the first clearance concave surface 1211 and the second clearance concave surface 131 cooperate to form a mounting cavity 111 that restricts the range of motion of the rotating component 300. Simultaneously, the first groove 1212 and the second groove 132 cooperate to form a hinge hole that rotatably engages with the shaft 331, allowing the rotating component 300 to rotate around the axis of the shaft 331. A portion of the rotating component 300 passes through the first clearance opening 112, facilitating the insertion of the rotating part 310 below the first clearance opening 112 for transmission engagement with the mating groove. The other end of the rotating component 300 passes through the second clearance opening 113, facilitating the connection of the connecting part 320 to the first massage head 20. This facilitates assembly.

[0041] Optionally, such as Figures 4 to 6 As shown, in some embodiments, the first support member 120 includes a first support body 121 having a first clearance concave surface 1211 and a first groove 1212, and a second support body 122 fixedly connected to the first support body 121. An eccentric wheel 220 is rotatably disposed on the second support body 122, such that the transmission part 213 and the mounting cavity 111 are spaced apart along a first direction. Thus, by utilizing the second support body 122, the rotational connection position of the eccentric wheel 220 is also spaced apart from the first mounting part 110, ensuring that the movement of the rotating member 300 relative to the support assembly 100 does not interfere with the eccentric wheel 220. This also facilitates the placement of the transmission part 213 below the mounting cavity 111, allowing one end of the rotating member 300 to pass through the first clearance opening 112, achieving the transmission engagement between the rotating part 310 and the transmission hole 201.

[0042] like Figure 4 as well as Figure 6As shown, in some embodiments, the support assembly 100 further includes a support shell 140. The support shell 140 is fixedly connected to the first support member 120 to form a protective cavity 101 for protecting the transmission assembly 200 and the rotating member 300. The mounting cavity 111 communicates with the protective cavity 101 through a first clearance opening 112. Thus, by using the support shell 140 and the first support member 120 to form the protective cavity 101, the transmission assembly 200 and the rotating member 300 can be effectively protected, improving the durability of the massage device 1.

[0043] It should be noted that there are various ways to connect the housing assembly 10 and the load-bearing assembly 100, including but not limited to screw fixing, snap fixing, welding fixing, adhesive fixing, and integral molding, etc.

[0044] Understandably, the shaft needs to rotate. The first and second grooves are partially circular holes.

[0045] In some embodiments, the support assembly 100 is assembled and fixed to the housing assembly 10. In this case, the connecting device 40 is modularly assembled onto the housing assembly 10 using the support assembly 100.

[0046] It should be noted that "assembly and fixing" includes, but is not limited to, screw fixing, snap fixing, welding fixing, etc.

[0047] In some embodiments, the first carrier 120 is integrally formed with the housing assembly 10. In this case, the structure of the connecting device 40 can be assembled onto the housing assembly 10 together with the power mechanism 30, etc.

[0048] Combination Figure 4 as well as Figure 6 In some embodiments, at least one of the bearing shell 140 and the second bearing body 122 is provided with a second mounting portion 1221 spaced apart from the first mounting portion 110 along a second direction. The second direction intersects the first direction, and the second mounting portion 1221 is rotatably connected to the eccentric wheel 220. Thus, by rotatably connecting the eccentric wheel 220 to the second mounting portion 1221 and engaging with the eccentric transmission of the transmission ring 212, the transmission portion 213 is also spaced apart from the transmission ring 212 along the second direction, which reduces motion interference between the rotating member 300 and the transmission ring 212 and the eccentric wheel 220.

[0049] like Figure 4 As shown, the first direction is the X-axis direction, and the second direction is the Z-axis direction.

[0050] It should be noted that there are various ways to achieve the rotatable connection between the second mounting part 1221 and the eccentric wheel 220, including but not limited to indirect rotatable connection via a rotating shaft. Alternatively, the eccentric wheel 220 may be fixed with a rotating shaft, and the second mounting part 1221 may be directly rotatably connected via the rotating shaft. This can be achieved through various conventional means, and no limitation is made here, as long as the rotatable connection requirement between the two is met.

[0051] like Figure 4 , Figure 6 as well as Figure 7 As shown, in some embodiments, the rotating part 310 can swing along the rotation axis direction close to or away from the eccentric wheel 220, and the transmission hole 201 is a cylindrical hole. A first conical concave surface 2011 for avoiding the rotating part 300 is provided within the cylindrical hole, and the first conical concave surface 2011 is located close to the eccentric wheel 220. And / or, a second conical concave surface 2012 for avoiding the rotating part 300 is provided within the cylindrical hole, and the second conical concave surface 2012 is located away from the eccentric wheel 220. Thus, through the transmission cooperation between the cylindrical hole and the rotating part 310, the rotating part 310 can slide along the cylindrical hole and also rotate relative to the cylindrical hole, thereby adapting to the eccentric movement of the transmission part 213 and the swinging of the rotating part 310, making the transmission cooperation between the two reliable.

[0052] Furthermore, such as Figure 4 , Figure 6 as well as Figure 7 As shown, in some embodiments, the rotating member 300 includes a hinge portion 330 hinged to the first mounting portion 110 and a first rod 340 fixedly connected to the hinge portion 330. The rotating portion 310 is disposed at the free end of the first rod 340. A first conical concave surface 2011 and a second conical concave surface 2012 are used to avoid the first rod 340. Thus, the rotation range of the rotating member 300 is limited by the hinge portion 330 hinged to the first mounting portion 110. Simultaneously, the first rod 340 passing through the first mounting portion 110 facilitates the transmission engagement between the rotating portion 310 and the transmission hole 201. During this process, the first conical concave surface 2011 and the second conical concave surface 2012 avoid the first rod 340, allowing the first rod 340 to reciprocate along the depth direction of the transmission hole 201 without interfering with the sliding of the rotating portion 310 relative to the transmission hole 201.

[0053] Based on the aforementioned shaft, the specific implementation of the hinge part includes having a shaft.

[0054] It should be noted that the power mechanism 30 can be implemented in various ways, including but not limited to a motor + gear transmission mechanism, a motor + belt transmission mechanism, a motor + chain transmission mechanism, etc. In one example, such as... Figure 8As shown, the power mechanism 30 includes a power source 31, a worm gear 32 that is driven by the power source 31, a worm wheel 33 that is driven by the worm gear 32, and a gear structure 34 that is driven by the worm wheel 33. The transmission assembly 200 is driven by the gear structure 34. Optionally, the driven gear of the gear structure 34 is coaxially driven by the eccentric wheel 220.

[0055] It should be noted that there is no limit to the number of the first massage heads 20, including but not limited to 1, 2, 3, etc., which can be flexibly designed according to actual massage needs.

[0056] like Figure 9 As shown, in some embodiments, the first massage head 20 can massage the neck of the human body. Two connecting devices 40 are spaced apart on both sides of the housing assembly 10. Two first massage heads 20 are also included, and each is connected to the connecting portion 320. Thus, the massage device 1 can massage the muscles on both sides of the neck, increasing the massage range and improving massage efficiency.

[0057] like Figure 9 As shown, in some embodiments, the massage device 1 further includes a second massage head 50, and the power mechanism 30 can drive the second massage head 50 to move.

[0058] It should be noted that the movement trajectory of the second massage head can be flexibly designed according to the curve of the body part to be massaged, as long as it can simulate the kneading massage effect of human hands. For example, when using the second massage head to massage the shoulders, it can move from the scapula towards the spine, and after reaching the first preset position, it can move towards the neck. After reaching the second preset position above the first preset position, it can move from the spine towards the scapula again. This process is repeated to achieve kneading. Of course, it can also move in the opposite direction, from the spine towards the scapula to the second preset position... Alternatively, the second massage head moves from the initial position down the rhomboid muscles (or other shoulder muscles) towards the back, then towards the spine, then towards the neck, and finally back to the initial position. This repeated motion achieves a kneading effect. Of course, the movement can also be reversed, moving from the initial position towards the neck… For example, when using the second massage head for a back massage, it can move from the side of the body towards the spine, reaching a first preset position, and then moving towards the neck. After reaching a second preset position above the first preset position, it then moves back from the spine towards the side of the body. This process is repeated to achieve kneading. Of course, the movement can also be reversed.

[0059] It should be noted that there is no limit to the number of the second massage heads, including but not limited to 1, 2, 3, etc., which can be flexibly designed according to actual massage needs.

[0060] For example, when the second massage head is used to massage the human shoulder, if there are two second massage heads, the movement of the second massage head can drive the two second massage heads to massage the upper and lower parts of the human shoulder simultaneously.

[0061] For example, when the second massage head is used to massage the back of the human body, if there are three second massage heads, the movement of the second massage head can drive the three second massage heads to massage the upper, middle and lower parts of the back at the same time.

[0062] It should be noted that "kneading massage" should be interpreted broadly, including back-and-forth swaying, back-and-forth rotation, and back-and-forth movement along a set trajectory. The massage intensity on the human muscles can be applied back and forth from light to heavy.
